Test

NOTE:

  • Check for DTCs. If any DTCs are stored, troubleshoot and clear them first.
  • Do not allow dust or other foreign particles to enter the port while installing the A/T oil pressure gauge.
  • Do not allow dust or other foreign particles to enter the inspection port.
  • Do not test pressure for more than 10 seconds at a time.
  • Do not change the transmission position/mode while raising the engine speed.
  • Be sure to check the transmission fluid level after each pressure test. When installing or removing the A/T oil pressure gauge, transmission fluid may run out of the inspection ports.
  • VSA DTC(s) may come on during the test-drive. If the VSA DTC(s) come on, clear the DTC(s) after testing is done with the HDS.

NOTE:

  • Driven pulley pressure may be above 5, 000 kPa (51.0 kgf/cm2, 725.2 psi) when there is a transmission problem that causes the PCM to go into fail-safe mode.
  • When troubleshooting, you must use the A/T high pressure gauge to measure driven pulley pressure.
  1. Remove the sealing bolt (A) with the sealing washer (B).
  2. Install the A/T high pressure gauge and the A/T pressure adapter to the driven pulley pressure inspection port.
